Process Heater as the name suggests are heaters that are in direct contact with the process.
In these types of the heater the process fluid enters from one end and this, in turn, passes through the heater and the heat generated by the heater is transferred to the process fluid through convection or radiant heat transfer and the process fluid leaves from the other end.
Electric tubular heaters fits almost every industrial heating applications ranging from immersion to air heating that requires temperatures of 1382 degree F
Duct heaters are heat transferring devices which are an assembly of heating elements mounted in a frame or duct.
Some of the typical applications of circulation heaters include heating of process water, soap and detergent solutions, Boiler and water heaters etc.
Flanged Immersion heaters due to there Lightweight, moisture proof, portable and easy installation and removal find applications in a wide range of area
Finned Tubular Heaters find applications in Convective Air & Gas Heating Dehumidification Curing Ovens and Plastic Dryers Organic Resins & Paint Curing etc.
The skids are generally used for pre heating the gas above its dew point, prior to feeding into the other equipment such as Gas operated turbines, generators or other process applications.
